1. Wind-controlled export of Antarctic Bottom Water from the Weddell Sea

   Recent studies suggest that the variability in Antarctic Bottom Water (AABW) properties in the Scotia Sea on time scales up to decadal may be linked to changes in the baroclinicity […]

2. Field reflectance spectroscopy of sparse vegetation cover on the Antarctic peninsula

   The results of a field spectroscopy campaign that aimed to provide ground truth data for validation of NDVI-based vegetation maps of the region around the British Antarctic Survey Rothera Research […]

3. Deformation and failure of the ice bridge on the Wilkins Ice Shelf, Antarctica

   A narrow bridge of floating ice that connected the Wilkins Ice Shelf, Antarctica, to two confining islands eventually collapsed in early April 2009. In the month preceding the collapse, we […]

5. Spatial distribution, habitat preference and colonization status of two alien terrestrial invertebrate species in Antarctica

   The introduction of invasive species is one of the greatest threats to Earth’s biodiversity, as they can reduce native biodiversity and alter ecosystem structure and function. Currently, the only two […]

6. History of sea ice in the Arctic

   Arctic sea-ice extent and volume are declining rapidly. Several studies project that the Arctic Ocean may become seasonally ice-free by the year 2040 or even earlier. Putting this into perspective […]

7. Temperature and precipitation history of the Arctic

   As the planet cooled from peak warmth in the early Cenozoic, extensive Northern Hemisphere ice sheets developed by 2.6 Ma ago, leading to changes in the circulation of both the […]

8. Potential and limitations of marine and ice core sea ice proxies: an example from the Indian Ocean sector

   Diatom assemblages in marine cores and sea salt deposition fluxes in ice cores have been used as sea ice proxies in the southern hemisphere. Here, a marine and an ice […]

9. Atmospheric decadal variability from high-resolution Dome C ice core records of aerosol constituents beyond the Last Interglacial

   Along the EPICA Dome C ice core, we measured concentrations of different water-soluble aerosol constituents and deduced total depositional flux records. Here we present high-resolution sodium, calcium, ammonium and nitrate […]

10. Ammonium and non-sea salt sulfate in the EPICA ice cores as indicator of biological activity in the Southern Ocean

    Sulfate (SO42-) and ammonium (NH4+) flux records over the last 150,000 years from both Antarctic EPICA ice cores (European Project for Ice Coring in Antarctica) are presented. The ice core […]

11. The protection of Antarctic terrestrial ecosystems from inter and intra-continental transfer of non-indigenous species by human activities: a review of current systems and practices

    Invasions by non-indigenous species are amongst the greatest threats to global biodiversity, causing substantial disruption to, and sometimes local extinction of, individual species and community assemblages which, in turn, can […]

12. Accidental transfer of non-native soil organisms into Antarctica on construction vehicles

    Antarctic terrestrial ecosystems currently include very few non-native species, due to the continent’s extreme isolation from other landmasses. However, the indigenous biota is vulnerable to human-mediated introductions of non-native species. […]
